HENRY BOUSHEAR, 015 FORT WILLIAM, ONTARIO, CANADA.

WATER-GAGE.

To all whom it may concern:

Be it known that I, HENRY BOUSHEAR, a subject of the King of England,and resident of Fort William P. O., in the Province of Ontario, in theDominion of Canada, have invented certain new and useful Improvements inTater-Gages, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to water glasses, and has for its object theproduction of a glass, which will allow its contents to be viewed from anumber of sides.

Another object of this invention is the production of a glass, the partsof which can be readily detached in case any of the same should becomebroken or fractured, and be replaced by new or unbroken parts.

WVith these and other objects in view this invention consists of certainnovel constructions, combinations and arrangements of parts as will behereinafter fully described and claimed.

In the drawings: Figure 1 is a perspective view of the gage glass. Fig.2 is a vertical section of the same taken through the glass plates. Fig.3 is a transverse section of the glass.

Referring to the drawings by numerals, 1 designates the housing orcasing, which is provided upon each end with a threaded aperture 2. Inthe apertures 2 are threaded plug devices 3, which plug devices areprovided with threaded sockets 4 adapted to be threaded upon thesuitable connecting pipes to the steam boiler. The plug devices 3 arealso provided with apertures 5, which communicate with the interior ofthe gage glass and allow the liquid to flow therein. The plug devices 3are provided upon the top thereof with a plurality of tooth portions 6,which are adapted to facilitate the rotation of the plug devices 3 andthe connecting of the same to the casing 1, and also to thecommunicating pipe of the steam boiler. The tooth portions 6 are adaptedto be engaged by a peculiarly constructed wrench, so as to allow thesame to be easily operated.

The casing l is provided with a plurality of side openings 7 and aplurality of side walls 8. The side walls 8 taper upon their inner sideswhich latter are covered with Specification of Letters Patent.

packing 9. The openings 7 in the walls of the casing or housing 1 areclosed by means of glass plates 10 for allowing the contents within theglass to be easily viewed from the outside thereof. The glass plates 10are firmly held within the openings 7 by means of clamp devices 11,which are substantially right angular in cross section. The clampdevices 11 are lined upon their glass-engaging surfaces with packing 12,and each clamp device 11 is firmly held in engagement with the glassplates 10 by means of a bolt-member 18, which passes through the sidewalls 8 and said bolt has a nut 14E threaded upon the outer end thereof,and, it will, therefore, be obvious that by tightening the nut 14 theclamp device 11 will be brought into binding engagement with the glassplates 10, thereby firmly clamping the same within the openings 7. Thebolts 13 are provided with screw heads 15, and by having such a headformed upon the bolt, it

will be obvious that the bolt will readily engage the clamp device.

From the foregoing description, it will be readily obvious that I haveprovided efficient means for firmly holding the glass plates 10 withinthe casing or housing 1 and that the same will be less likely to break,for the reason that the glass plates are at all times engaged by thepacking both upon the side walls 8 and also upon the clamp devices 11.

What I claim is 1. In an indicator of the class described a housingprovided with a plurality of side openings, said casing lined withpacking, plates positioned within said casing and adapted to close saidside openings, clamp devices positioned within said housing and engagingsaid glass plates for'holding the same firmly within said openings, andbolts passing through said clamp devices and housing for firmly holdingthe clamp devices in engagement with said glass plates.

2. A device of the class described com prising a housing, said housingprovided with a plurality of side openings, glass plates closing saidopenings and allowing the interior of said housing to be viewed from theoutside, clamp devices substantially right angular in cross sectionengaging said glass plates, bolts passing through In testimony whereof Ihereunto aflix my said clarnp devices and housing and prosignature inpresence of two Witnesses. vided with threaded outer ends extendingHENRY BOUSHEAR' outside of said housing, and a nut threaded upon thethreaded end of each of said bolts Witnesses:
